Rithum and Lutron Electronics announced integrated support for Lutron RadioRA 3 inside Rithum’s smart home platform, delivered through a new Rithum Pro Plugin.

The integration brings RadioRA 3 lighting and Sivoia motorized shading into Rithum — giving RadioRA 3 installations a touchscreen control point at the wall plus full climate control, multiroom audio, and broad SIP intercom and CCTV support.

“RadioRA 3 has been one of the most-requested integrations from our installer community since it launched, and we’re proud to deliver it,” said Ryan Ovens, CEO at Rithum.

What the Plugin Adds for RadioRA 3 Installs

The Rithum Pro Plugin adds a visual touchscreen layer to RadioRA 3 installs with fine dimming, shade positioning and dynamic scene selection, all being acessible from the same wall panel. Rithum is also hubless, meaning the processor sits inside every Rithum Switch and Rithum Switch Pro.

“Lutron’s keypads provide elegant, intuitive control. What Rithum adds is a sleek touchscreen control point on the wall, fine dimming when you want it, and a full smart home platform around RadioRA 3 — climate, audio, intercoms and CCTV all in the same environment,” adds Ovens.

Alongside RadioRA 3 lighting and Lutron shading, the Rithum Switch also controls full climate; multiroom audio; and broad SIP intercom and CCTVs, with macro scenes able to tie everything together. One tap can trigger a RadioRA 3 lighting scene alongside a shade move, a temperature change and music in the room, according to the company.

“Rithum offers a smart home platform where RadioRA 3 can sit naturally alongside full climate, audio, intercom and CCTV control — exactly the kind of installer experience we want RadioRA 3 specified into,” said Ben Bard, Vice President, Luxury Residential at Lutron Electronics. “We’re pleased to welcome them into the RadioRA 3 ecosystem.”

When paired with a RadioRA 3 system, Rithum also pulls existing scenes, circuits, zones and shades directly from the Lutron processor, keeping in sync. When adding a zone, renaming a scene or re-tune a dimming curve, Rithum will reflect it automatically.
